SAFETY-RAZOR.

SPECIFICATION forming part of Letters Patent No. 786,898, dated April11, 1905. Appncaaon inea Juiy 7,1904.. serial no'. 215,602.

To all whom t may concern:

Be it known that I, BENJAMIN HrEsoHEELD,

a resident of Pittsburg, in the county of Alle-- ghen y and State ofPennsylvania, have invented a new and useful Improvement in Safety-Razors; and Ido hereby declare the following to be a full, clear, andexact description thereof. l

My invention relates to safety-razors, and more especially to that classof razors in which the blade is adapted to fold back, so as to beinclosed by the handle.

The object of my invention is to provide a safety-razor of this style inwhich the razor may be used equally well with or without the guard, theguard being adapted to be inclosed within the handle and to be movedindependently of the blade.

A further object of my invention is to iprovide for an adjustment of theguard or shield, so as lto provide `for the wear on the blade of therazor in grinding or honing.

,To these ends my invention comprises the novel features hereinafter setforth and claimed.

To enable others Skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure 1 is a view offmy improved razor with one side of thehandle removed, showing one of the guards in position within the handleand the other guard engaging the open blade. Eig. 2 is an enlarged viewof the inner portion of the blade and the meansfor adjusting the guardthereon. Fig. 3 is a crosssection at the pivotal point of the razor, andFig. 4 is a View of the pin for pivoting the blade and guard to thehandle.

Like numerals indicate like parts in each of the figures.

In the drawings the numeral 2 designates a suitable handle formed ofbone, metal, or other suitable material, said handle being composed oftwo parts, with the intervening s pace 8 for the reception of the bladeand the guards. The handle-sections are connected at one end by therivet 4 and at the opposite end by the ins 5 said in having an enlaro'edcenter circular portion 6 and the reduced end portions 7, having twoflat opposite sides. This pin 5 passes through a circular opening 8 inthe razor-blade 9, while the attened end portions 7 pass through theapertures 10 in the inner end of the shield or guard 11. These apertures10 are circular in form and communicate with each other by means ofpassages 12. The flattened end portions7 also pass through the handleportions 2 of the razor, when said pin is then riveted, as at 13, tohold the parts together, while at the same time the pin 5 is preventedfrom turning` within the handle. terposed between the guards 11 and thehandle portions 2 are the washers 14.

The two guards llare'preferably employed, as it enables the guards to beadjusted for use in either hand. These guards, as illustrated, arearranged on opposite sides of the blade and are constructed of suitablespring metal with the toothed or corrugated portion 15, the teeth 16 ofsaid corrugated portion having their ends turned, as at 17. At the outerend of the corrugated portion 15 of the guard is the clip 18, which isadapted to move in the seat 19 in the end of the guard, the outer-end ofsaid clip being turned inwardly, as at 20, so as to engagethe blade ofthe razor when the guard is adjusted for use. The clip 18 is formed ofspring Inetal and fits. snugly Within the seatl 19, so that a certainamount of resistance is offered' to the movement of said clip in saidseat. Where the corrugated portion 15 of the guard is unitedV with themain body portion, as at 21, there is a slight shoulder formed on saidguard, which 'causes the corrugated portion'15 to conform to the shapeof the blade of the razor, which ordinarily has a slight curve from itsupper edge to the cutting edge. This enables the guard to fit snuglyover the razor-blade. Y

As hereinbefore stated, thepin 5 has its flattened end portions 7passing through lthe projections 10 in the inner end of the guard. Thisprovides for the adjustment of the guard where the razor has become Wornby grinding or honing. By this construction the guard may be adjustedevenly for its entire length, for by throwing the guard at right anglesto the blade or handle, as indicated in dotted lines in Fig. 1, theconnecting-passages 12 between the apertures 10 are brought intoposition to slip past the flattened end portions 7 of the pin 5, so thatsaid guard may be moved to bring the pin 5 into engagement with one ofthe other apertures 10, so as to change the position of the guard withreference to the blade, when the guard is again thrown down intoposition to engage the blade. In order to more securely retain the guardin place when in position for use, the guard is provided with a slightprojection 22, which is adapted to swing into and engage the seats ordepressions 23, formed in the razor-blade. This will prevent the guardfrom slipping when in use.

As stated, preferably two guards are employed, and, as indicated in Fig.1, the guard not in use is folded back within the handle, the hookedportions 17 of the teeth of said guard engaging the edge of one of thehandle portions. In the same manner when the ra- Zor is not in use theother guard engages the edges of the other handle portion while theblade is inelosed between the guards. In this way when the razor is notin use it is to all appearances like the ordinaryrazor of thischaracter, and in case it is not desired to use the guards therazor-blade may be operated entirely independent of the guards, and whenit is desired to use the guards it is simply necessary to withdraw oneof the guards and adjust in any position which may be taken veryquickly, and the projection 22 on the guard engages the properdepression 23, while at the same time the clip 18 is adjusted so as toengage the cutting edge of the razor. In this manner the guard is heldsecurely in position. In ease the party using the razor does not shaveequally well with one hand the guard in use may be folded back into thehandle and the other guard brought out, so as to suit the convenience ofthe party using the razor. By the form of the adjustment illustrated ofthe guard the guard is adjusted equally for its entire length, so thatas the blade of the razor is worn down the guard may be adjusted tosuit.

When the parts of the razor are folded within the handle, the razor maybe inserted in a case of the ordinary size. No eXtra parts are required,while at the same time the person owning suchl a razor has a razor whichmay be used equally well with or without the safety device.

What I claim is- 1. In a safety-razor, the combination with the handle,of a blade pivoted therein, a swinging guard mounted in said handle onthe same pivotal point as said blade, and

means for adjusting said guard equally throughout its length withreference to said blade.

2. ln a safety-razor, the combination with a suitable handle, of a bladepivoted therein, a swinging guard mounted therein, said guard havingteeth adapted to engage the edge of the razor-handle.

3. In a safety-razor, the combination with a suitable handle, of a bladepivotcd therein, a swinging guard having apertures formed therein, saidapertures being connected by contracted passages, the pivotal pin uponwhich said blade and guard are mounted having a flattened end portionwith which the apertures in said guard engage.

4. In a safety-razor, the combination with a suitable handle, of a bladepivotcd therein, a swinging guard, and pivotal pin having a circularportion engagingthe said razor-blade and a attened end portion adaptedto engage the apertures formed in said guard, said apertures havingcontracted passages connecting same.

5. In a safety-razor, the combination with a suitable handle, of a bladepivoted therein, a swinging guard mounted in said handle and aspring-clip in said guard adapted to engage the cutting edge of saidblade.

6. In a safety-razor, the combination with a suitable handle, of a bladepivoted therein, a swinging guard mounted in'said handle, said guardhaving a seat formed in its outer end and a spring-clip engaging saidseat and adapted to engage the cutting edge of said blade.

7 In a safety-razor, the combination of a suitable handle, of a bladepivotcd therein, a swinging guard mounted therein, a pivotal pinsupporting said blade and guard having a flattened end portion adaptedto engage apertures formed in said guard, said apertures havingcontracted passage-ways connecting the same, said guard having aprojeetion thereon adapted to engage one of a series of depressionsformed in said blade.

8. In a safety-razor, the combination with a suitable handle, of a blademounted therein, two swinging guards mounted in said handle on oppositesides of said blade adapted to enter said handle from the opposite sideat which said blade enters said handle and having teeth adapted toengage the edges of said handle.

In testimony whereofl I, the said BENJAMIN HIRsoI-IFELD, have hereuntoset my hand.
